Typical temperature stability of a laser diode mounted in a LDM-4982M is better than 0.1°C for for one hour. Thermal resistance between the mount thermistor and internal package thermistor was calculated to be between 10°C/W and 6°C/W depending upon temperature. Using devices with an internal thermistor will allow the user to monitor the temperature of the device to prevent the laser from being operated over the temperature limit.
